Cai Gou-Qiang's sculpture uses twisted human forms to show motion. The front figure is leanign towards one side and it is balanced by having its left leg lifted up. This figure shows motion because viewers anticipate his fall. It is an anticipated motion since the figure's upper body is shifted all the way to his right side and the weight is over his right leg. This week, we learned about the illusion of motion. This figure illustrates the idea that even though it is a still sculpture, viewers can feel the anticipated fall.
